How to watch the full "strawberry" moon — the last supermoon of 2021
CBSN
From a lunar eclipse to a partial solar eclipse to supermoons, 2021 has been a spectacular year for lunar events. But this month marks the year's final supermoon, with the full "strawberry" moon illuminating the night sky this week.
A supermoon occurs when the moon is at its closest point to Earth in its orbit, known as perigee. It appears slightly larger and brighter than a typical full moon. However, scientists have yet to agree on exactly how to officially classify the phenomenon, so there is some disagreement as to whether June's moon counts as a supermoon. "For 2021, some publications consider the four full Moons from March to June, some the three full Moons from April to June, and some only the two full Moons in April and May as supermoons," NASA's Gordon Johnston said.More Related News
